We aren't likely to get to work on this any time soon. We don't have enough resources. The code in question is now in elf/setup-vdso.h, and I would be more than happy to review a patch that fixes this bug. You'd need to run the testsuite on master to make sure you don't introduce any regressions and then show that LD_DEBUG=all still works, and that the debugger which was previously reporting bogus warnings doesn't report any more bogus warnings. The best possible patch avoids this hack: + if (GLRO(dl_debug_mask)) + l->l_name = copy; and instead adjusts the debug code to inform the user that this DSO has no associated file e.g. a virtual dso.
